Reporting high sensitivity in the near infrared (NIR) range and high operational stability, the S9251 series silicon avalanche photodiodes fit a variety of applications, including range-finding and spatial light transmission. Four devices in the series cover a spectral response range of 440 nm to 1,100 nm and specify a peak photosensitivity of 0.52 A/W at 860 nm and a peak quantum efficiency (QE) of 72% at 900 nm. Typical dark current is 0.1 nA for the S9251-02, 0.2 nA for the S9251-05, 0.4 nA for the S9251-10, and 0.8 nA for the S9251-15. Both the S9251-02 and S9251-05 have a 400 MHz cutoff frequency, while the S9251-10 and S9251-15 have cutoff frequencies of 380 MHz and 350 MHz, respectively. Effective active areas range from 0.2 mm in diameter for the S9251-02 to 1.5 mm in diameter for the S9251-15. Operating temperature for each device is –20°C to +85°C. Prices start at $32.56 each in OEM quantities. HAMAMATSU CORP., Bridgewater, NJ. (800) 524-0504.
